I was going to do a mix this afternoon and went to get everything together. I keep all my ingredients in a closet in a plastic bin and the VG itself on the floor (it's a gallon jug). I picked the jug of VG up and noticed the top had come loose (like it popped loose). I still had to twist it once around to take it off, though. The VG itself seems to be the same level of viscosity it has always been and I didn't see anything floating in it. There's honestly no telling how long that cap had been like that, though. Would it be recommended to buy a new jug or would you guys try using it? If it helps, it feels like there's not much humidity in my apartment (I usually have the air set to 78). Thanks for any information!
